Facebook, Amazon and IBM are among the tech companies touring the Flatiron, Chelsea and Meatpacking areas, hoping to drum up between 40,000 and 120,000 square feet in the tightest market in the country, where rents are already higher than in newer Midtown buildings.

When Facebook moved into 40,000 square feet at 335 Madison Ave. from nearby 340 Madison last year, the Midtown location seemed at odds with its start-up culture.

But brokers say tech companies also need fast access to bankers, ad agencies and transportation, and that West Coast-based tech companies, in particular, are more likely to be in parts of the city that are not in Google’s West Chelsea shadow.

“Facebook expanded last year and announced New York as an engineering office in addition to sales and marketing,” said James Wenk of Jones Lang LaSalle, who is not involved in these searches but represents other tech firms looking for space.

Wenk said both Facebook and Amazon are “perpetually” in the market as they tweak their needs and roll up other startups, such as Facebook’s $1 billion purchase of Instagram earlier this month.

IBM leases space in several parts of the city, and Wenk noted that to attract younger employees a Chelsea/Flatiron space “would be a smart move.”

CBRE brokers are representing IBM, while Facebook is touring with Newmark Grubb Knight Frank and Amazon with Cresa Partners. When e-mails or calls were returned, the answer was “no comment.”

An old Tootsie Roll factory at 325 West Broadway may finally get a life as a long-awaited condo conversion.

Sources said the nearly 60,000-square-foot building is being marketed on behalf of Lehman Bros. by HFF and should sell for around $500 a square foot, or $30 million. Bids will be due in May.

Edge Fund Advisors has won the bidding for 4 New York Plaza at $270 a square foot, sources said.

The 1.1 million-square-foot building is being sold by Harbor Group International and marketed by Darcy Stacom and William Shanahan at CBRE, who didn’t return requests for comment.

The Daily News and JPMorgan Chase rent most of the building, which was bought from the bank in 2010.

Edge completed the purchase of the office space at 1540 Broadway just last year.

Calls and e-mails were not returned for comment.

Crystal company Swarovski is adding to the city’s luster.

Sales are so brisk at its tiny shop in Times Square that the company is seeking a second location in the area, according to its broker, RKF’s Robert Cohen.

“We’re landlocked,” he said of the company’s 788 square feet in the center of Vornado Realty Trust’s 1540 Broadway retail spread, where the Italian chain Buca di Beppo will soon be installed in a portion of the Planet Hollywood space.

To better reach potential customers in the Grand Central district of Midtown, Cohen said Swarovski has also signed a lease for 1,400 square feet at 365 Madison Ave. in the base of the Roosevelt Hotel.

Gary Alterman, also of RFK, represented the hotel in this deal, which had an asking rent of $275 a square foot.
